Ocean acoustic tomography — The western North Atlantic showing the locations of two experiments that employed ocean acoustic tomography. AMODE, the Acoustic Mid Ocean Dynamics Experiment (1990 1), was designed to study ocean dynamics in an area away from the Gulf Stream,… … Wikipedia

Acoustic thermometry — of Ocean Climate (ATOC) is an idea to observe the state of the world s oceans, and the ocean climate in particular, using long range acoustic transmissions. Prototype measurements of temperature have been made in the North Pacific Basin and… … Wikipedia

Tomography — Basic principle of tomography: superposition free tomographic cross sections S1 and S2 compared with the projected image P Tomography refers to imaging by sections or sectioning, through the use of any kind of penetrating wave. A device used in… … Wikipedia

Acoustic neuroma — 1. A benign tumor that may develop on the hearing and balance nerves near the inner ear. The tumor results from an overproduction of Schwann cells small sheet like cells that normally wrap around nerve fibers like onion skin and help support the… … Medical dictionary
